“Laser Induced
Breakdown Spectroscopy -LIBS”
Abstract:
The technique
of LIBS (also known under the name of Laser Micro Analysis – LMA or LIPS –
Laser Induced Plasma Spectroscopy) offers a simple, fast, real-time method of
elemental analysis. Any material, solid, liquid or gaseous can be analyzed, and
none or only very little sample preparation is needed. Detection limits for
solid samples are usually in the range of a few tens part per million. LIBS
utilizes the high power densities obtained by focusing the radiation from a
pulsed, fixed frequency laser to generate a luminous micro-plasma from solid,
liquid or gaseous samples in the focal region. The plasma composition, which is
representative for sample composition is detected. In the thirty years or so
since its conception the potential of LIBS as an analytical tool has been
realized both for qualitative and quantitative analysis in the laboratory and
industrial environments, respectively.
In the
presentation the basic methodology of LIBS and its selected applications will
be discussed.
